201209692 六、發明說明： 本申請案主張於2010年8月27日申請的日本專 請案20^90804號及於同日申請的日本專利申社 2〇1〇-胸37號的優先權，該些先前申請案的全文以弓月用 的方式併入本文。 【發明所屬之技術領域】 本發明是有關於-種呈現觸感的裝置，尤其是關於— 種根據對觸控感測器（tGuehSe_)的接觸來呈現觸感的 【先前技術】 近年來，於行動電話等的行祕射，作為檢測操 者的操作的操作部或開關（switch)等的輸入裝置，有辞 採用具備觸控©板（tGueh Panel)或觸朗關等的觸控感 ^的輸入裝置。除了行動終端以外，於桌上型計算機： 票機等的資訊機ϋ或電子爐⑽ge)、電視機、照明器里 等的家電製品、產業用機器（工薇生產自動化（細叫 AUtomation，FA)機器）等中，具備觸控感測器的 置亦得到廣泛使用。 # 、於此種觸控感測器中，已知有電阻膜方式、靜電容方 式、光學式等的各種方式。尤其，行動電話等的小型的炊 多具備如下所述的觸控面板，~，該觸控面板例如 ，數子小鍵盤(numerickeypad)等的按鍵（key)或圖符 icon)等作為目標（Gbj’eet)㈣示於顯示部上並 觸控感測料檢測操作者對該目標的接觸。 4 201209692 具備此種觸控面板的終端裝置可根據啟動的應用軟體 (application software)，而藉由目標的顯示來構成各種用 戶介面（user interface)。因此，對於操作者而言，操作簡 便易懂，因此具備觸控面板的終端裝置急速地普及。 ^然而，任一方式的觸控感測器均是檢測由手指或觸控 筆（stylus pen)而來的接觸，觸控感測器自身即使被觸碰， 亦不會如機械式按鈕開關那般產生物理位移。因此，操作 者即使對觸控感測器進行操作，亦無法獲得針對該操作的 反饋（feedback)。因此，操作者無法獲得進行操作時對按 ，或按鈕的「按下/解除按下」的操作感。因此，於此類終 端中，操作者易在相同位置進行多次接觸等的反覆操作， 有時會對操作者造成應力（stress) 0 因此，亦提出有一種當觸控感測器檢測出接觸時，使 觸控感測器振動的反饋方法（例如，參照專利文獻丨及 利文獻2)。 先前技術文獻 專利文獻 專利文獻1:曰本專利特開2003_288158號公報 專利文獻2 :日本專利特開2008-130055號公報 然而，例如，於靜電容方式的觸控感測器中，使微弱 的，流流經透_導電絲於觸控感測㈣整個表面形成 電，’並捕獲操作者的手指等接觸該導電膜的位置的表面 電荷的變化ϋ此來進行位置檢測。此時，靜電容方式的 觸控感測n根_蚊制靜電容减動的微弱的電流的 201209692 變化來求出該接觸的位置。 於具備此種靜電容方式的觸控感測器的觸感呈現裝置 中，為了使觸控感測器振動以對操作者提供觸感之類的反 饋’必須將用於發生振動的驅動機構設置於觸控感測器的 附近。並且，當將此種驅動機構設置於觸控感測器的附近 時，必須使該驅動機構儘可能靠近觸控感測器而設置至接 觸該觸控感測器的程度。其原因在於，若非如此，則驅動 機構產生的振動將無法充分傳遞至觸控感測器，由此，會 產生觸控感測器的振動所消耗的電力的一部分被浪費的問 題。而且，尤其在行動電話之類的小型終端裝置中，亦存 在下述問題，即，由於内部空間（space)的限制等，亦必 須將產生振動的驅動機構靠近觸控感測器而設置。 然而，若為了使觸控感測器振動而將例如壓電元件之 類的觸感呈現部設置於觸控感測器附近，則會產生因使壓 電元件振動時施加的電壓所造成的電場。如上所述，觸控 感/則器疋根據微弱的電流的變化來求出接觸的位置。因 此，當產生此種電場時，會存在下述問題，即，即使該電 場微弱’但仍會對觸控感測器對接觸的位置的檢測造成不 良影響。亦即，當為了對操作者提供反饋而施加用於驅動 觸感呈現部的電壓時’觸控感測器會受到影響，因此有可 能不能準確地檢測接觸的位置。 因此’透過近年來的研究，正在推進一種觸控面板的 開發’、該馳面板對於提供反饋時_呈現部所產生的電 場造成的雜訊（nGise)具有—定程度的耐性，且具備可檢 6 201209692 測，觸的位置的檢測機構。而且，亦正在推進例如以下技 術等的研究，該技術是對為了檢測接觸的位置而流有電流 的掃描線的形狀進行反覆研究等，以消除（eaneei)雜訊 的技術。進而，當將液晶顯示面板（panel)等的顯示部重 合於觸控感測器而使用時’亦會自該顯示部產生雜訊，但 藉由使用適當的靜電容數位轉換.器或雜訊抑制演算 (algorithm)，從而可消除一定程度的雜訊。 然而，即使是該些觸控感測器，當將壓電元件之類的 觸感呈現部緊_㈣測H而設置時，仍不足以認為不會 p電場的不良影響。其在於，觸控制^原本便^ 接受來自外部的影響（作用）以檢測該影響（作用）者， 測接觸的位置的精度變得良好，要求觸控感測 器具備一疋程度的靈敏度。 【發明内容】 有鑒於上述情況而完成的本發明的目的在於提供 觸感呈現裝置，其可降低職的呈現對觸控感測 檢測造成的影響。 1 徵在^述目的之第1觀點的觸感呈現裝置的發明的特 觸控感測器； 觸感呈現。卩，#近上述觸控❹指*配 控感測器振動； 文豕觸 ，控感測H控制部’對上述觸控感測器發送掃 说，並且自該觸贼測轉收上述掃描㈣，藉此來檢^ 201209692 對上述觸控感測器的接觸的位置； 信號線，在上述觸控感測器與上述觸控感測器控制部 之間傳遞掃描信號；以及 觸感控制部，根據上述觸控感測器控制部所檢測出的 上述接觸的位置來控制上述觸感呈現部，以使上述觸控感 測器振動， 上述觸感呈現部配置在不與上述信號線重合的部位。 第2觀點的發明是如第i觀點的觸感呈現裝置， 其中將上述觸控感測器設為靜電容方式的觸控感測 器。 而且，達成上述目的之第3觀點的觸感呈現裝置的發 明的特徵在於包括： 觸控感測器； 觸感呈現部，使上述觸控感測器振動 ;以及 觸感控制部’用來進行控制，使進行掃描的時間區間、 與上述觸感呈現部使上述觸控感測器振動的時間區間不相 重合’上述掃描是用於檢測對上述觸控感測器的接觸的位 置。 第4觀點的發明是如第3觀點的觸感呈現裝置， 其中將上述觸控感測器設為靜電容方式的觸控感測 器。 第5觀點的發明是如第3觀點的觸感呈現裝置， 。其中上述觸感控制部在使上述觸控感測器振動的時間 區間内施加驅動電壓，以使上述觸感呈現部發生振動。 8 201209692 發明的效果 根據本發明’觸感的呈現對觸控感測器的位置檢測造 成的影響得以降低，觸控感測器能夠以高精度來進行接觸 的位置的檢測。 【實施方式】 以下’參照圖式來說明本發明的各實施形態。 (第1實施形態） · 圖1是表示本發明的第1實施形態的觸感呈現裝置的 概略結構的功能方塊圖。本實施形態的觸感呈現裝置可適 用於任意裝置，只要是基於藉由觸控感測器來檢測操作者 的接觸以進行動作即可，例如可適用於行動電話或遊戲機 等的行動終端、或者設置在銀行的自動提款機（Automatic Teller Machine，ATM)、設置在車站的售票機等。 如圖1所示，本實施形態的觸感呈現裝置丨具備基板 10、觸控感測器11、觸感呈現部12、信號線16及信號線 18、觸控感測器控制部2〇以及觸感控制部％。再者，觸 控感測器控制部20是包括掃描信號產生部22及位置檢測 部24而構成。而且，觸感控制部3〇是包括驅動信號產生 部32而構成。 在本實施形態中’基板10被配置在包括後述的液晶面 板等的顯示部的前表面。為了可目測該顯示部的顯示，較 佳為於基板10中，使與顯示部的進行顯示的部位對應的部 分具有透過性。於基板1〇的前表面，於該具有透過性的部 分’典型上配置有片（sheet)狀且具有透過性的觸控感測 201209692 器η。 觸控感測器11是具有觸控面的感測器，對操作者的手 指等接觸（觸碰（touch))觸控面的情況進行檢測。該觸 控感測器Π通常包括例如電阻膜方式、靜電容方式、光學 式等的方式的觸控感測器，而本實施形態中採用靜電容方 式的觸控感測器。當觸控感測器11為靜電容方式時，通常 具備包含方格狀的X電極及Y電極的感測器部。該感測器 部可在電極間蓄積電能。在未對觸控感測器u造成接觸的 狀態下，感測器部的2個電極生成穩定的電場。然而，當 人的手指靠近或接觸時，由於人體所帶有的導電性，手指 將起到接地（earth)的作用，因此電場會發生變化，而手 指所觸碰的部分的靜電容值將減少。根據該靜電容值的變 化，觸感呈現裝置1可檢測對觸控感測器u的接觸的位 置。再者，於圖1中，僅示出觸控感測器u的χ電極及γ 電極的一部分。 而且，觸控感測器11藉由將觸控面設為透過型，並配 置於未圖示的顯示部的前表面，從而亦被用作對操作者觸 碰（接觸）顯示部上顯示的按鍵或按鈕等的目標的情況進 行檢測的感測器（所謂的觸控面板）。此處，未圖示的顯示 部描繪並顯示按鈕、按鍵或圖符（ic〇n )等的目標（〇bj ）， 例如可使用液晶顯示面板或有機電致發光 (Electr〇luminescence , EL)顯示面板等而構成。如此， 觸感呈現裝置1於顯示部上顯示按鍵或按鈕等的目標，且 刼作者進行對該目標的接觸時，在與該目標對應的觸控感 201209692 測器11上的位置處檢測該接觸。再者，於本實施形， 對於觸感呈現裝置〗賴减湘u配置於齡部的前表 面’並基於針軸㈣上顯我目標的位置的接觸來進 動作的情況，與公知技術者並無_不㈤讀，因 圖示及詳細說明。 觸感呈現部12是使觸減測ϋ 11振動者，-般可使 • 1各種_呈現部’而在本實施形態中是使用㈣振動元 =(壓電1)來構成。於本實麵g巾，職呈現部η ^佳為充分靠近觸控感測H u而配置， 1 十對觸控感測器11的振動。此時，觸感呈現部 定配置於基板1G的不具透過性的部分，即， 酉己=基板U)上的除了觸控感測器u的接觸檢測區域及 現重合的區域以外的部分。於圖1中，觸感呈 ^12在基板1G上靠近馳感測器u的上部而配置。若 觸感呈現部12所產生的振動將充分傳遞至觸控感 測器11。即，可使觸感呈現部12所產生 % 傳遞至觸控感測器Ul?f7造成的電力的浪費受^抑制。刀 觸控感測器控制部2G全面控制操作者對觸控感列器 董觸Λ觸的位置的檢測。觸控感測器控制部2G為了進行 對觸控感測II H的接觸的位置的檢測，而自掃描 in向觸控11㈣極供給掃描錢以進行掃°描。 的對自掃描信號產生部22向觸控感測器U 電極所供給的掃描信號的靜電容的變化進_測 、，位置檢測部24自觸控感測心接收上述婦描信號。 201209692 藉此，觸控感測器控制部20可檢測出對觸控感測器11的 接觸的位置，並輸出位置資訊作為其結果。此種靜電容感 測技術可使用公知者，因此省略更詳細的說明。 於本實施形態中，如圖1所示，信號線16自觸控感測 器控制部20 (更詳細而言，為掃描信號產生部22)朝向觸 控感測器11傳遞掃描信號。進而，信號線18自觸控感測 器11朝向觸控感測器控制部20 (更詳細而言，為位置檢 測部24)傳遞掃描信號。此種信號線16及信號線18例如 可使用可撓性（flexible)配線（可撓性電纜（flexible cable)) 等。再者，於圖1中，將信號線16及信號線丨8予以簡化 而示出。 觸感控制部30全面控制觸感呈現部12呈現觸感的動 作。具體而言，觸感控制部30在收到觸感呈現的指示時， 自驅動信號產生部32向觸感呈現部12供給驅動信號。根 據該驅動信號’觸感呈現部丨2使觸控感測器11振動，藉 此來對操作者呈現規定的觸感。於本實施形態中，觸感控 制部30根據觸控感測器控制部2〇所檢測出的對觸控感測 器11的接觸的位置來控制觸感呈現部12,以使觸控感測 器11振動。例如，為了在檢測出操作者針對與顯示部上顯 示的目標對應的觸控感測器Η的位置的接觸之後，告 作者開始與該目標相_的規定處理,感㈣部％ j 觸感呈現部12使觸控感測器η振動。 部 如上所述’若為了使觸減測H u振動 12設置於觸減 11 _近，則會產㈣使觸感Ϊ 12 201209692 現部12振動時施加的電壓引起的電場，從而使觸控感測器 11的檢測接觸的位置的精度會發生惡化。因此，於本實施 形態中，如圖1所示，將觸感呈現部12配置在不與上述信 號線16及信號線18重合的部位。 如此’觸感呈現部12既不與信號線16重合，亦不與 信號線18重合，而採用一定程度地隔開的配置結構，藉 此’即使觸感呈現部12進行觸感的呈現（即，振動的產 生），因此而產生的電場對觸控感測器11的位置檢測造成 的影響亦可降低。因此，觸感呈現裝置1能夠以高精度來 檢測對觸控感測器11的接觸的位置。 圖2是表示本實施形態的觸感呈現裝置中的觸感呈現 部的配置的另一例的圖。圖2所示的觸感呈現裝置2是在 圖1所說明的第1實施形態的觸感呈現裝置1中，對觸感 呈現部的配置進行變更。其他的概略結構可採用與第i實 施形態的觸感呈現裝置1同樣的結構。 於圖2中 不出了配置有2個觸感呈現部的結構的觸 感呈現裝置。圖2所示的觸感魏裝置2在觸控感測器^ 的左侧配置有觸感呈現部12A，並且在觸控感測器 侧^置有觸感呈現部12B。因此，與圖^斤示的結構相比， 呈現觸感。 於該配置、構中，信號線16及信 觸感呈現部i2A及觸感呈現部12Β重，-=不與 置結構中，因觸感呈現部i2Α及觸感呈°因此’於此種配 產生的電場對觸控感測器的位置檢測所造==: 13 201209692 降低。因此，觸感呈現裝置2亦能夠以高精度來檢測姆觸 控感測器11的接觸的位置。 (第2實施形態） 其次，對本發明的第2實施形態的觸感呈現裝置進行 說明。第2實施形態是在圖1及圖2所說明的第1實施形 態的觸感呈現裝置中，對觸感呈現部或信號線丨6、丨8的配 置進行變更。其他的概略結構可採用與第1實施形態的觸 感呈現裝置i或觸感呈現裝置2同樣的結構。因此，於本 實施形態中，適當省略與第丨實施形態中說明的内容相 的說明。 一般而言，亦可設想下述情況，即，由於構成觸感呈 現裝置的裝置的框體内部的構造，而無法採用如在第i實 施形態中以圖1或圖2所說明般的、信號線16及信號線 18完全不重合於觸感呈現部12的配置。而且，可設想下 述情況，即，由於設計觸感呈現裝置時所用的各構成元件 的大小或形狀等的規格的限制，亦無法採用信號線16及信 號線18完全不重合於觸感呈現部12的配置。因此，於第 2實施形態中，對在無法採用如第1實施形態般的信號線 16及彳§说線18完全不重合於觸感呈現部12的配置的愔沉 下採取的對策進行說明。 於上述第1實施形態中，使用靜電容方式的觸控感測 器11，根據流經該觸控感測器11的微弱的電流所引起的 k號的變化’來進行操作者對觸控感測器11的接觸的位置 的檢測。具體而言，自掃描信號產生部22經由信號線16 201209692 向觸控感測器11傳遞掃描卢 由信號線18向位置檢測部2=’而且自觸控感測器U經 用於檢測_城測it u’藉此來進行 遞至角iir 掃描信號產生部22、經由信號線16傳 生成後，基本U錄生部22 描信號。另—方面，自』=的影響的信號強度高的掃 至位罟;|A、、a^ 觸控感測器.11經由信號線18傳遞 的掃描I因ST:知描信號由於已結束了觸控感測器11 ，田㈣會因經由人體的靜電容而發生變化。而且可 ^的^^測器U經由信號線18而傳遞至位置檢測 會自機哭j5號由於跨及了相對較長的路徑而傳遞，因此 °。内。卩的各元件而受到各種電磁波等帶來的影響。 1如，於圖、3所示的觸感呈現裝置5巾，自觸控感測 向觸控感測器控制部20傳遞掃描信號的信號線18 5於配置在觸控感測器Π的右側的觸感呈現部12B。若 ，用此種配置結構’則可奴，已受到各種影響的掃描信 號在經由信號線18而傳遞時，會進一步受到觸感呈現部 12Β所產生的電場的影響，從而無法以高精度來檢測對觸 控感測器11的接觸的位置。然而，亦可設想下述情況，即， 由=裝置的框體内部的構造上的限制等的要因，而無法採 用k號線16及信號線18該兩者完全不重合於觸感呈現部 12的配置。 ^ 因此’於第2實施形態中，當由於各構成元件的規格 等的限制，而不得不將信號;線16或信號線18中的任一者 15 201209692 以重合於觸感 重合於觸感呈· 12祕置時，信號線18 呈現部12的方式而配置。 β例如於圖4所示的觸感呈現裝置3中，自觸控感測 朝向觸控感測器11傳遞掃描信號的信號線16 口於$呈現部12B。然而，自觸控感測器u朝向觸控 感測器控制，2°傳遞掃描信號的信號線18並未重合於觸 感呈現。卩*採肖此種配置結構’貞化到各種影響的掃 描信號在經由信號線18而傳遞時，不會進一步受到觸感呈 現部12B所產生的電場的影響。因此，於觸感呈現裝置3 中，對觸控感測器11的接觸的位置的檢測時的精度不會大 為劣化。 其-人，於第2實施形態中，對在無法採用信號線16 及信號線18完全不重合於觸感呈現部12的配置的情況下 採取的對策的其他示例進行說明。 於圖5所示的觸感呈現裝置6中’自觸控感測器u 朝向觸控感測器控制部20傳遞掃描信號的信號線18重合 於配置在觸控感測器11的下側的觸感呈現部12。若採用 此種配置結構，則可設想，已受到各種影響的掃描信號在 經由h號線18而傳遞時，會進一步受到觸感呈現部12所 產生的電場的影響，從而無法以高精度來檢測蚜觸控感測 器11的接觸的位置。然而，亦可設想下述情況，即，由於 裝置的框體内部的構造上的限制等的要因，而不得不將觸 感至現部12設為圖5所示的配置。 在此種情況下，於第2實施形態中’信號綠18以重合 201209692 於觸感呈現部12的方式而配置。 例如，於圖6所示的觸感呈現裝置4中，自觸控感測 器控制部20朝向觸控感測器11傳遞掃描信號的信號線16 重合於觸感呈現部12。然而，自觸控感測器11朝向觸控 感測器控制部20傳遞掃描信號的信號線18並未重合於觸 感呈現部12。若採用此種配置結構，則已受到各種影響的 掃描信號在經由信號線18而傳遞時，不會進一步受到觸感 呈現部12所產生的電場的影響。因此，於觸感呈現裝置4 中，對觸控感測器11的接觸的位置的檢測時的精度不會大 為劣化。 (第3實施形態） 其次’對本發明的第3實施形態的觸感呈現裝置進行 說明。圖7是表示本發明的第3實施形態的觸感呈現裝置 的概略結構的功能方塊圖。 如圖7所示，本實施形態的觸感呈現裝置7具備觸抑 感測器11、觸感呈現部12、觸控感測器控制部2〇以及^ 感控制部30。再者’觸控感測器控制部20是包括掃推^ 號產生部22及位置檢測部24而構成。而且，觸感控^苦5 30是包括驅動信號產生部32而構成。上述各功能部可1 用與圖2中說明的構成第1實施形態的觸感呈現裝置2 " 各功能部大致同樣者。因此’省略上述各功能部的詳《 明。 =、、、田說 於本實施形態的觸感呈現裝置7中，觸感控制部 可自觸控感測器控制部20接受掃描信號產生部22供終^ 17 201209692 描信號的時序（timing)的通知。 圖8⑷、® 8⑻、圖8 (C)是用於說明本實施形 態的觸感呈現處理的概念圖。圖8 是說明先前的觸感 呈現的代表例的圖。 先前’由於無法以太高的速度來進行檢測對觸控感測 器的接觸的位置的處理等的情況，因而—般如圖8(A)的 上段所示，用於檢測接觸的位置的掃描是以跨及規定的長 期間，例如以始終掃描的方式來進行。於圖8(A)的上段， 於導通（ON)驗置存在實__表示供給有用於進行 掃描的信號。在此種狀況下，如圖8 (A)的下段所示為 了使觸控感測II產生振動，在自⑴至⑴為止的期間， 產生例如使觸感呈現部之__機構進行驅動的信號 j驅動信號）。於圖8⑷的下段，於導通的位置存在實 線的期間表示供給有驅動信號。然而，自

(C)的下段所示般，以不與進行檢測接觸的位置的掃 間㈣相重合的方式，來產生用於使觸控感測器產 生振動的驅動信號。 即，本實施形態的觸感控制部3〇進行控制，使進行掃 描的時間區間、與觸感呈現部12使觸控感測器u振動的 時間區間不相4合，上述掃描是麟檢測_控感測器i i 的接觸的位置。藉由此種控制，在使觸控感測器u振動的 時間區間内，不進行用於檢測對觸控感測器丨i的接觸的位 置的掃描’因此’使振動產生的驅動信號起到作為雜訊的 作用的原因而對掃描造成不良影響將不會發生。 於本實施形態的觸感呈現裝置7中，如圖7所說明般， 觸感控制部30可自觸控感測器控制部2〇接受掃描信號產 生部22將掃描信號供給至觸控感測器11的時序的通知。 藉由該通知，觸感控制部30可在事前或即時（realtime) 獲知觸控感測器控制部20的掃描信號產生部22產生掃描 k號的時序。因此，根據如此掌握的掃描信號產生部22 產生掃描信號的時序，觸感控制部30對時序進行控制，以 201209692 避免由驅動信號產生部32產生的驅動信號在時間上與掃 描信號的產生相重合。即，觸感控制部3〇將時序控制/成， 即使收到呈現觸感的指示，但在產生掃描信號的^間區間 内，不自驅動信號產生部32供給驅動信號，而在未產生掃 描信號的時間區間内，使上述驅動信號產生。根據以此方 式受到控制的時序，觸感控制部30在使觸控感測器u振 動的時間區間内施加驅動電壓，以使觸感呈現部12產生振 動。 再者’於圖7所示的本實施形態的觸感呈現裝置7中， 设想觸感控制部3〇自觸控感測器控制部2〇接受供給掃描 信號的時序的通知的情況而進行了說明。然而，本實施形 態的觸感呈現裝置7並不限定於此種結構。例如，觸感控 制部30亦可採用直接接收掃描信號產生部22朝向觸控^ 測器11產生的掃描信號的結構，從而可即時掌握產生掃描 信號的時序。 (第4實施形態） 其次’對本發明的第4實施形態的觸感呈現裝置進行 說明。圖9是表示本發明的第4實施形態的觸感呈現裝置 的概略結構的功能方塊圖。如圖9所示，第4實施形態的 觸感呈現裝置8是在圖7所說明的第3實施形態的觸感呈 現裝置7中更具備主機控制器（host controller) 40。其 他的概略結構可採用與第3實施形態的觸感呈現裝置7同 樣的結構。因此，於本實施形態中，適當省略與第3實施 形態中說明的内容相同的說明。 20 201209692 於觸感呈現裝置8中，由於具備主機控制器4〇，因此 與上述第3實施形態的觸感呈現裝置7不同的是，觸感控 制部30無須自觸控感測器控制部2〇接受供給掃描信號的 時序的通知。主機控制器4〇接收觸控感測器控制部2〇檢

INSTRUCTIONS: This application claims the priority of Japanese Patent Application No. 20^90804, which was filed on August 27, 2010, and Japanese Patent Application Co., Ltd. No. 2, No. 37, which was applied for on the same day. The full text of the previous application is incorporated herein by reference. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for presenting a tactile sensation, and more particularly to a prior art that presents a tactile sensation according to contact with a touch sensor (tGuehSe_). In the case of an operation device such as an operation unit or a switch that detects an operator's operation, the touch device has a touch sensor with a touch panel (tGueh Panel) or touch-sensitive touch. Input device. In addition to the mobile terminal, it is used in desktop computers, information machines such as ticket machines, electronic appliances (10) ge, home appliances, and industrial equipment such as televisions and illuminators (automation of UNIDO, FA) In the case of a machine or the like, a device having a touch sensor is also widely used. # 。 In such a touch sensor, various methods such as a resistive film method, a static capacitance method, and an optical type are known. In particular, a small mobile phone or the like has a touch panel as described below, and the touch panel is, for example, a key or icon icon such as a numeric keypad (Gbj). 'eet' (4) is shown on the display portion and the touch sensing material detects the operator's contact with the target. 4 201209692 A terminal device equipped with such a touch panel can form various user interfaces by means of target display according to the launched application software. Therefore, since the operation is simple and easy for the operator, the terminal device having the touch panel is rapidly spreading. ^ However, any type of touch sensor detects contact by a finger or a stylus pen. Even if the touch sensor itself is touched, it will not be like a mechanical button switch. Physical displacement is produced as usual. Therefore, even if the operator operates the touch sensor, feedback for the operation cannot be obtained. Therefore, the operator cannot obtain an operation feeling of "pressing/depressing" of pressing , or button when performing an operation. Therefore, in such a terminal, the operator can easily perform repeated operations such as multiple contacts at the same position, which sometimes causes stress to the operator. Therefore, there is also proposed a touch sensor that detects contact. A feedback method for vibrating the touch sensor (for example, refer to Patent Document No. 2). PRIOR ART DOCUMENT PATENT DOCUMENT Patent Document 1: Japanese Patent Laid-Open Publication No. Hei. No. 2008-130055. However, for example, in a capacitive touch sensor, it is weak, The flow passes through the through-conducting wire to form electricity on the entire surface of the touch sensing (4), and captures a change in the surface charge of the position of the operator's finger or the like that contacts the conductive film, thereby performing position detection. At this time, the static capacitance type touch sensing changes the position of the contact by the 201209692 change of the weak current of the n-mosquito static capacitance reduction. In a tactile sense presentation device having such a capacitive touch sensor, in order to vibrate the touch sensor to provide a tactile sensation to the operator, it is necessary to set the drive mechanism for generating vibration. In the vicinity of the touch sensor. Moreover, when such a driving mechanism is disposed in the vicinity of the touch sensor, the driving mechanism must be disposed as close as possible to the touch sensor to the extent that the touch sensor is touched. The reason for this is that if this is not the case, the vibration generated by the driving mechanism cannot be sufficiently transmitted to the touch sensor, whereby a part of the power consumed by the vibration of the touch sensor is wasted. Further, particularly in a small terminal device such as a mobile phone, there is also a problem that the drive mechanism that generates vibration must be placed close to the touch sensor due to restrictions in the internal space or the like. However, if a tactile sensation portion such as a piezoelectric element is placed in the vicinity of the touch sensor in order to vibrate the touch sensor, an electric field caused by a voltage applied when the piezoelectric element vibrates is generated. . As described above, the touch sensor/receiver 求出 determines the position of the contact based on the change in the weak current. Therefore, when such an electric field is generated, there is a problem that even if the electric field is weak, the detection of the position of the contact by the touch sensor is adversely affected. That is, when the voltage for driving the tactile sensation portion is applied in order to provide feedback to the operator, the touch sensor is affected, so that it is possible to accurately detect the position of the contact. Therefore, 'through recent research, we are advancing the development of a touch panel', which has a certain degree of tolerance and is detectable for the noise (nGise) caused by the electric field generated by the presentation part when feedback is provided. 6 201209692 Test, the detection mechanism of the position of the touch. In addition, research is being carried out, for example, on the technique of repeating research on the shape of a scanning line in which a current flows in order to detect the position of contact, and to eliminate noise. Further, when a display portion such as a liquid crystal display panel is used in combination with a touch sensor, noise is generated from the display portion, but by using an appropriate electrostatic capacitance digital conversion. Or noise suppression algorithm (algorithm), which can eliminate a certain amount of noise. However, even these touch sensors are not sufficiently considered to have no adverse effect of the p electric field when the tactile sensation portion such as the piezoelectric element is set tightly. The touch control is originally required to accept an external influence (action) to detect the influence (action), and the accuracy of the position at which the contact is measured becomes good, and the touch sensor is required to have a degree of sensitivity. SUMMARY OF THE INVENTION An object of the present invention, which has been made in view of the above circumstances, is to provide a tactile sensation presenting device which can reduce the influence of a job presentation on touch sensing detection. 1 A special touch sensor of the invention of the tactile sensation presenting device of the first aspect of the present invention;卩,# Near the above touch finger* is equipped with the sensor vibration; the file touch, the control H control unit sends a sweep to the touch sensor, and the scan is received from the touch thief (4) In order to check the position of the contact of the touch sensor by the 201209692; the signal line, the scan signal is transmitted between the touch sensor and the touch sensor control unit; and the tactile sense control unit, The touch sensing presentation unit is controlled to vibrate the touch sensor according to the position of the contact detected by the touch sensor control unit, and the touch sensing presentation unit is disposed at a portion that does not overlap with the signal line. .

[Embodiment] Hereinafter, each embodiment of the present invention will be described with reference to the drawings. (First Embodiment) Fig. 1 is a functional block diagram showing a schematic configuration of a tactile sensation presenting device according to a first embodiment of the present invention. The tactile sensation presenting device of the present embodiment can be applied to any device, and can be operated by detecting an operator's contact by a touch sensor, and can be applied to, for example, a mobile terminal such as a mobile phone or a game machine. Or set up at the bank's Automatic Teller Machine (ATM), ticket machine installed at the station, etc. As shown in FIG. 1 , the tactile sense presentation device of the present embodiment includes a substrate 10 , a touch sensor 11 , a tactile sense presentation unit 12 , a signal line 16 and a signal line 18 , and a touch sensor control unit 2 . Touch control unit%. Further, the touch sensor control unit 20 includes a scan signal generating unit 22 and a position detecting unit 24. Further, the tactile sensation control unit 3 includes a drive signal generating unit 32. In the present embodiment, the substrate 10 is disposed on the front surface of a display unit including a liquid crystal panel or the like which will be described later. In order to visually display the display portion, it is preferable that the portion corresponding to the portion where the display portion is displayed is made transparent in the substrate 10. On the front surface of the substrate 1 ,, the permeable portion is typically provided with a sheet-like and transparent touch sensing η. The touch sensor 11 is a sensor having a touch surface for detecting a situation in which an operator's finger touches (touches) the touch surface. The touch sensor Π generally includes a touch sensor such as a resistive film method, a capacitive method, or an optical type, and in the embodiment, a capacitive sensor is used. When the touch sensor 11 is in the capacitive mode, it is usually provided with a sensor portion including a square X electrode and a Y electrode. The sensor portion can accumulate electrical energy between the electrodes. The two electrodes of the sensor portion generate a stable electric field in a state where contact is not made to the touch sensor u. However, when a person's finger is close to or in contact, due to the electrical conductivity of the human body, the finger will function as an earth, so the electric field will change, and the electrostatic capacitance of the portion touched by the finger will decrease. . According to the change in the electrostatic capacitance value, the tactile sensation presenting device 1 can detect the position of the contact with the touch sensor u. Furthermore, in FIG. 1, only the χ electrode and a part of the γ electrode of the touch sensor u are shown. Further, the touch sensor 11 is also disposed on a front surface of a display unit (not shown) by using the touch surface as a transmissive type, and is also used as a button for touching (contacting) the display on the display unit. A sensor (so-called touch panel) that detects the target of a button or the like. Here, the display unit (not shown) draws and displays a target (〇bj) such as a button, a button, or an icon (ic〇n), and can be displayed, for example, by using a liquid crystal display panel or an organic electroluminescence (EL) display. It is composed of a panel or the like. As described above, the tactile sensation presenting device 1 displays a target such as a button or a button on the display unit, and when the author makes contact with the target, the contact is detected at a position on the touch sensor 201209692 corresponding to the target. . Furthermore, in the present embodiment, in the case where the tactile sensation device is disposed on the front surface of the aging portion and is based on the contact of the position on the needle axis (four), it is known to a person skilled in the art. No _ no (five) reading, due to the illustration and detailed description. The tactile sensation presentation unit 12 is configured to vibrate the tactile enthalpy 11 and generally has a plurality of _presentation portions. In the present embodiment, (four) vibrating elements = (piezoelectric 1) are used. In the real surface g towel, the job presentation unit η ^ is preferably placed close to the touch sensing H u , and the ten pairs of the touch sensor 11 vibrate. At this time, the tactile sensation portion is disposed on the non-transmissive portion of the substrate 1G, that is, the portion other than the contact detecting region of the touch sensor u and the region where the touch is present, on the substrate 1). In Fig. 1, the tactile sensation is placed on the substrate 1G close to the upper portion of the sensor u. The vibration generated by the tactile sensation presentation portion 12 is sufficiently transmitted to the touch sensor 11. That is, the waste of power generated by the % generated by the tactile sensation presentation portion 12 to the touch sensors U1 to f7 can be suppressed. The knife touch sensor control unit 2G comprehensively controls the operator's detection of the position of the touch sensor. In order to detect the position of the touch sensing II H, the touch sensor control unit 2G supplies scanning money from the scan in to the touch 11 (four) pole for scanning. The change in the electrostatic capacitance of the scan signal supplied from the scan signal generating unit 22 to the touch sensor U electrode is measured, and the position detecting unit 24 receives the above-described smear signal from the touch sensing core. 201209692 Thereby, the touch sensor control unit 20 can detect the position of the contact with the touch sensor 11, and output the position information as a result thereof. Such a static capacitance sensing technique can be used by a known person, and thus a more detailed description will be omitted. In the present embodiment, as shown in Fig. 1, the signal line 16 transmits a scanning signal from the touch sensor control unit 20 (more specifically, the scanning signal generating unit 22) toward the touch sensor 11. Further, the signal line 18 transmits a scan signal from the touch sensor 11 toward the touch sensor control unit 20 (more specifically, the position detecting unit 24). As such a signal line 16 and a signal line 18, for example, a flexible wiring (flexible cable) or the like can be used. Further, in Fig. 1, the signal line 16 and the signal line 丨 8 are simplified. The tactile sensation control unit 30 comprehensively controls the action of the tactile sensation presentation unit 12 to present a tactile sensation. Specifically, when the tactile sensation control unit 30 receives an instruction to present the tactile sensation, the self-driving signal generating unit 32 supplies a drive signal to the tactile sensation presentation unit 12. The touch sensor 11 is caused to vibrate according to the drive signal 'the tactile sense presentation unit 2', thereby presenting a predetermined tactile sensation to the operator. In the present embodiment, the tactile sensation control unit 30 controls the tactile sensation presentation unit 12 based on the position of the contact of the touch sensor 11 detected by the touch sensor control unit 2 to make the touch sensing. The device 11 vibrates. For example, in order to detect the contact of the operator with respect to the position of the touch sensor 对应 corresponding to the target displayed on the display unit, the author begins the prescribed process with the target, and the sense (4) % j touch is presented. The portion 12 vibrates the touch sensor η. As described above, if the touch-down measurement Hu vibration 12 is set to the touchdown 11 _ near, the (4) touch Ϊ 12 201209692 current electric field caused by the voltage applied at the time of 12 vibration, so that the touch feeling The accuracy of the position at which the detector 11 detects contact is deteriorated. Therefore, in the present embodiment, as shown in Fig. 1, the tactile sensation presentation unit 12 is disposed at a portion that does not overlap with the signal line 16 and the signal line 18. Thus, the tactile sensation presentation unit 12 does not overlap with the signal line 16 and does not overlap with the signal line 18, and adopts a configuration structure that is spaced apart to some extent, whereby the haptic presentation portion 12 performs the tactile sensation (ie, The vibration is generated, and the influence of the electric field generated on the position detection of the touch sensor 11 can also be reduced. Therefore, the tactile sensation presenting device 1 can detect the position of the contact with the touch sensor 11 with high precision. Fig. 2 is a view showing another example of the arrangement of the tactile sensation presenting unit in the tactile sensation presenting device of the embodiment. The tactile sensation presentation device 2 shown in Fig. 2 is configured to change the arrangement of the tactile sensation presentation unit in the tactile sensation presentation device 1 of the first embodiment described with reference to Fig. 1 . The other schematic configuration can be the same as that of the tactile sensation presenting device 1 of the i-th embodiment. In Fig. 2, a tactile sense presentation device having a structure in which two tactile sense presentation portions are arranged is not shown. The tactile sensation device 2 shown in Fig. 2 is provided with a tactile sensation presentation portion 12A on the left side of the touch sensor, and a tactile sensation presentation portion 12B is disposed on the touch sensor side. Therefore, the tactile sensation is presented as compared with the structure shown in the figure. In this arrangement and configuration, the signal line 16 and the letter-feeling presentation unit i2A and the tactile sensation presentation unit 12 are heavy, and in the case of the non-incompatible structure, the tactile sense presentation unit i2 and the tactile sensation are in a range of The generated electric field is reduced by the position detection of the touch sensor ==: 13 201209692. Therefore, the tactile sensation presenting device 2 can also detect the position of the contact of the touch sensor 11 with high precision. (Second Embodiment) Next, a tactile sensation presenting device according to a second embodiment of the present invention will be described. In the second embodiment, in the tactile sensation presenting device of the first embodiment described with reference to Figs. 1 and 2, the arrangement of the tactile sense presenting unit or the signal lines 丨6 and 丨8 is changed. The other schematic configuration can be the same as that of the touch sensing device i or the tactile sensation device 2 of the first embodiment. Therefore, in the present embodiment, the description of the contents described in the third embodiment will be omitted as appropriate. In general, it is also conceivable that a signal as described in FIG. 1 or FIG. 2 in the i-th embodiment cannot be used due to the structure inside the casing of the device constituting the tactile sensation presenting device. The line 16 and the signal line 18 do not overlap the arrangement of the tactile sense presentation unit 12 at all. Further, it is conceivable that the signal line 16 and the signal line 18 are not completely overlapped with the tactile sense presentation portion due to limitations in the specifications of the size or shape of each constituent element used in designing the tactile sensation presenting device. 12 configuration. Therefore, in the second embodiment, the countermeasures taken in the case where the signal line 16 and the line 18 in the first embodiment are not overlapped with the arrangement of the tactile sense presentation unit 12 are not described. In the first embodiment described above, the touch sensor 11 of the capacitive type is used to perform an operator's sense of touch based on the change of the k number caused by the weak current flowing through the touch sensor 11. Detection of the position of the contact of the detector 11. Specifically, the self-scanning signal generating unit 22 transmits the scanning louver signal line 18 to the position detecting portion 2=' to the touch sensor 11 via the signal line 16201209692 and is used for detecting the _city from the touch sensor U. After the measurement is performed, the basic U-recording unit 22 generates a signal, and the basic U-recording unit 22 traces the signal. On the other hand, the signal intensity from the influence of 』= is high to the position 罟; |A, a^ touch sensor. The scan I transmitted via the signal line 18 is changed by the static capacitance of the human body due to the completion of the touch sensor 11 due to the ST: the known signal. Moreover, the U can be transmitted to the position detection via the signal line 18. The self-machine crying j5 is transmitted because it crosses a relatively long path, so °. Inside. Each element of the crucible is affected by various electromagnetic waves and the like. For example, in the tactile sense presentation device 5 shown in FIG. 3, the signal line 185 for transmitting the scan signal from the touch sensing to the touch sensor control unit 20 is disposed on the right side of the touch sensor Π The tactile sensation presentation part 12B. If such a configuration is used, the scan signal that has been subjected to various influences is further affected by the electric field generated by the tactile sense presentation unit 12 when transmitted through the signal line 18, so that it cannot be detected with high precision. The position of the contact of the touch sensor 11. However, it is also conceivable that the k-line 16 and the signal line 18 cannot be used at all by the factor of the structural limitation inside the casing of the device, and the two do not overlap the tactile sense presentation portion 12 at all. Configuration. Therefore, in the second embodiment, the signal is not limited by the specifications of the respective constituent elements, etc., and any of the lines 16 or the signal lines 18 201209692 overlaps the touch to the tactile sensation. • When 12 is secret, the signal line 18 is arranged in the manner of the presentation unit 12. For example, in the tactile sensation presenting device 3 shown in Fig. 4, the signal line 16 for transmitting the scanning signal from the touch sensing toward the touch sensor 11 is at the presentation portion 12B. However, since the touch sensor u is directed toward the touch sensor, the signal line 18 that transmits the scan signal at 2° does not coincide with the touch presentation. In the case of such an arrangement structure, the scanning signals which are degraded to various influences are not further affected by the electric field generated by the tactile sensation portion 12B when transmitted via the signal line 18. Therefore, in the tactile sensation presenting device 3, the accuracy in detecting the position of the contact of the touch sensor 11 is not greatly deteriorated. In the second embodiment, a description will be given of another example of measures taken when the arrangement of the signal line 16 and the signal line 18 does not overlap the tactile sense presentation unit 12 at all. In the tactile sense presentation device 6 shown in FIG. 5 , a signal line 18 that transmits a scan signal from the touch sensor u toward the touch sensor control unit 20 is superposed on the lower side of the touch sensor 11 . The tactile sensation presentation unit 12. According to this configuration, it is conceivable that the scanning signal that has been subjected to various influences is further affected by the electric field generated by the tactile sensation portion 12 when transmitted via the h-line 18, so that it is impossible to detect with high precision. The position of the contact of the touch sensor 11. However, it is also conceivable that the touch to the present portion 12 has to be set as shown in Fig. 5 due to factors such as structural limitations of the inside of the casing of the apparatus. In this case, in the second embodiment, the signal green 18 is arranged so as to overlap the 201209692 in the tactile sense presentation unit 12. For example, in the tactile sense presentation device 4 shown in Fig. 6, the signal line 16 that transmits the scan signal from the touch sensor control unit 20 toward the touch sensor 11 is superposed on the tactile sense presentation unit 12. However, the signal line 18 that transmits the scanning signal from the touch sensor 11 toward the touch sensor control unit 20 does not overlap the touch sensing portion 12. According to this arrangement configuration, the scanning signals that have been subjected to various influences are not further affected by the electric field generated by the tactile sense presenting portion 12 when transmitted via the signal line 18. Therefore, in the tactile sensation presenting device 4, the accuracy in detecting the position of the contact of the touch sensor 11 is not greatly deteriorated. (Third Embodiment) Next, a tactile sensation presenting device according to a third embodiment of the present invention will be described. Fig. 7 is a functional block diagram showing a schematic configuration of a tactile sensation presenting device according to a third embodiment of the present invention. As shown in Fig. 7, the tactile sensation presenting device 7 of the present embodiment includes a haptic sensor 11, a tactile sensation presenting unit 12, a touch sensor control unit 2A, and a sensation control unit 30. Further, the touch sensor control unit 20 includes a sweep generating unit 22 and a position detecting unit 24. Further, the tactile sensation control 5 is constituted by including the drive signal generating unit 32. Each of the functional units 1 described above can be substantially the same as the functional units of the tactile sensation presenting device 2 " of the first embodiment described in Fig. 2; Therefore, the detailed description of each of the above functional units is omitted. In the tactile sense presentation device 7 of the present embodiment, the tactile sensation control unit can receive the timing of the scanning signal generation unit 22 from the touch sensor control unit 20 for the end of the signal. announcement of. Figs. 8(4), 8(8), and 8(C) are conceptual views for explaining the tactile sensation presenting process of the present embodiment. Fig. 8 is a view for explaining a representative example of the previous tactile sensation. Previously, since the processing for detecting the position of contact with the touch sensor cannot be performed at a too high speed, the scanning for detecting the position of the contact is generally as shown in the upper part of FIG. 8(A). It is carried out over a long period of time, for example, by always scanning. In the upper stage of Fig. 8(A), the presence of a true __ indicates that a signal for scanning is supplied. In such a situation, as shown in the lower part of FIG. 8(A), in order to cause the touch sensing II to vibrate, a signal for driving the __ mechanism of the tactile sense presenting portion is generated during the period from (1) to (1). j drive signal). In the lower stage of Fig. 8 (4), the period in which the solid line is present at the on position indicates that the drive signal is supplied. However, as far as _, as mentioned above, due to the role of driving money, it will have an adverse effect on scanning. The processing to the position of the contact of the touch sensor can be performed at a non-directional speed. Therefore, for checking the description, for example, even in the upper section of FIG. 8(B): the intermittent scanning of the raw: can also obtain a sufficiently good knot = also short 2: the case of the valley type touch sensor Next, the position of the above contact can be detected by scanning the position of the contact every several tens of microseconds. Detecting the touch sensor However, even if the sweep is performed intermittently as shown in the upper part of Fig. 8 (8), the clock is generated by intermittently detecting the position of the _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Money, there will be a question ^, at this time, the period from (1) to Ρ) and the number from (5) to (4) will act as a noise, so it will still be = two, therefore, this In the embodiment, as shown in the upper part of Fig. 8(c), the position detection is performed by intermittent scanning, and further, as shown in the lower part of Fig. 8 (C), the position is not in contact with the detection. The sweeping chambers (4) coincide with each other to generate a driving signal for causing the touch sensor to vibrate. In other words, the tactile sensation control unit 3 of the present embodiment controls the time interval in which the scanning is performed and the time interval in which the tactile sensation presentation unit 12 vibrates the touch sensor u, and the scanning is the detection of the _ Control the position of the contact of sensor ii. With such control, during the time interval in which the touch sensor u is vibrated, the scanning for detecting the position of the contact with the touch sensor 丨i is not performed, so that the driving signal generated by the vibration is made to function. Adverse effects on scanning as a cause of noise will not occur. In the tactile sense presentation device 7 of the present embodiment, as described with reference to FIG. 7, the tactile sensation control unit 30 can receive the scan signal from the touch sensor control unit 2 to supply the scan signal to the touch sensing device. Notification of the timing of the device 11. With this notification, the tactile sensation control unit 30 can know the timing at which the scan signal generating unit 22 of the touch sensor control unit 20 generates the scan k number in advance or real time. Therefore, according to the timing at which the scan signal generating unit 22 thus generates the scan signal, the tactile sensation control unit 30 controls the timing to prevent the drive signal generated by the drive signal generating unit 32 from coincident with the generation of the scan signal by 201209692. . In other words, the tactile sensation control unit 3 controls the timing, and even if an instruction to present the tactile sensation is received, the drive signal is not supplied from the drive signal generating unit 32 in the interval in which the scan signal is generated, but no scan is generated. The above drive signal is generated during the time interval of the signal. According to the timing controlled in this manner, the tactile sensation control unit 30 applies a driving voltage in a time interval in which the touch sensor u is vibrated to cause the tactile sensation presentation unit 12 to vibrate. In the tactile sense presentation device 7 of the present embodiment shown in FIG. 7, it is assumed that the tactile sensation control unit 3 has received notification of the timing of supplying the scan signal from the touch sensor control unit 2 Description. However, the tactile sensation presenting device 7 of the present embodiment is not limited to such a configuration. For example, the tactile sense control unit 30 can also directly receive the scan signal generated by the scan signal generating unit 22 toward the touch sensor 11, so that the timing at which the scan signal is generated can be grasped in real time. (Fourth Embodiment) Next, a tactile sensation presenting device according to a fourth embodiment of the present invention will be described. Fig. 9 is a functional block diagram showing a schematic configuration of a tactile sensation presenting device according to a fourth embodiment of the present invention. As shown in Fig. 9, the tactile sensation presenting device 8 of the fourth embodiment further includes a host controller 40 in the tactile sensation presenting device 7 of the third embodiment described with reference to Fig. 7 . Other schematic configurations can be the same as those of the tactile sensation presenting device 7 of the third embodiment. Therefore, in the present embodiment, the same description as that described in the third embodiment will be omitted as appropriate. 20 201209692 In the tactile sense presentation device 8, since the host controller 4 is provided, unlike the tactile sense presentation device 7 of the third embodiment, the tactile sensation control unit 30 does not need to be self-touch sensor control unit 2 〇 Accept the notification of the timing of supplying the scan signal. The host controller 4 receives the result of the position where the touch sensor control unit 2 detects the contact with the touch sensing. When the result is received, the host controller 4 is based on the finger of the application software, according to the position of the contact with the touch sensor 11. It is determined whether or not the tactile sensation control unit 30 is instructed to present a tactile sensation. #, the host controller 4 grasps the display state of the display unit (not shown) disposed on the surface side of the touch sensor 11, and determines that the touch position of the touch sensor 11 is slightly correct. The location of the target of the sensation. The host controller 40 issues an indication of the tactile sensation to the tactile sensation control unit in the case where the position of the contact with the touch sensor 11 corresponds to the position of the target to which the tactile sensation should be presented. On the other hand, the host controller 40 does not present the presence of the touch control unit 3 even if the touch sensor detects a contact, but the position of the clear does not correspond to the position of the target to be reduced. An indication of tactile sensation. Further, the host controller 4 can also supply the scan signal by the notification from the touch sensor control unit. Therefore, the host controller 40 is in the touch control unit 3. When the presentation touch is issued, the scan signal generation unit 22 is also notified to supply the scan signal batch #. Therefore, in the present embodiment, the tactile sensation control unit 30 also causes the timing gate to receive an instruction to present a tactile sensation, but supplies the drive to the drive signal generation unit 32 in the inter-time & Signal while on 21 201209692 Λ. The above drive signal is generated in a time interval in which no scan signal is generated. . Further, in the present embodiment, as in the third embodiment, the touch control unit 30 receives the notification of the timing at which the scan signal generation unit 22 supplies the scan signal from the touch sensor control unit 2'. The tactile sensation control unit may also control the timing at which the drive signal is generated from the drive signal generating unit 32. Further, in the present embodiment, the host controller 40 has grasped the timing at which the scan signal generating unit 22 supplies the scan signal at the timing when the tactile sensation control unit 3 is instructed to present the tactile sensation. Therefore, the timing control of the drive signal generated in the time zone in which the scan signal is not generated may be performed by the host controller 40 instead of the touch control unit 3?. Further, in the tactile sensation presenting device 8 of the present embodiment shown in FIG. 9, it is assumed that the tactile sensation control unit 30 receives the notification of the timing of supplying the scan signal from the host controller 40. However, this embodiment The tactile sensation presenting device 8 is not limited to such a configuration. For example, similarly to the description in the third embodiment, the tactile sensation control unit 30 can directly receive the scanning signal generated by the scanning signal generating unit 22 toward the touch sensor 11, so that the scanning signal can be instantly grasped. Timing. (Fifth Embodiment) Next, a tactile sensation presenting device according to a fifth embodiment of the present invention will be described. FIG. 10 is a functional block diagram showing a schematic configuration of a tactile sensation presenting device according to a fifth embodiment of the present invention. As shown in Fig. 10, the tactile sensation presenting device 9 of the fifth embodiment further includes a load detecting unit 14 in the tactile sensation presenting device 8 of the fourth embodiment described with reference to Fig. 9 . The other schematic configuration can be basically the same as that of the tactile sensation presenting device 8 of the fourth embodiment. In the present embodiment, the same description as that described in the above embodiments is omitted as appropriate. In the present embodiment, the load detecting unit 14 detects the pressing load on the touch surface of the touch sensor 11. The load detecting unit 14 is configured by, for example, a strain gauge sensing element that is linearly reacted with respect to radiation. In the above-described embodiments, the timing at which the contact with the self-contact is detected at a position corresponding to the target to be displayed on the display unit, and the feeling of the touch control unit 3 is expressed. The form of the instruction has been explained. However, if the touch is sensed at the time of detecting the contact, even if the operator unconsciously touches the sensor u, it will present _. Such a device not only starts some processing according to the operator's unconscious operation, but also does not give the author the actual button (or (4)) touch when pressed (the touch of the button is pressed). . Therefore, in order to present a realistic tactile sensation to the operator, the tactile sensation presenting device 9 stimulates the tactile sensation from the state of smashing the pressure of the author by performing the action as described below. In other words, the tactile sensation presenting device 9 stimulates the pressure feeling of the operator until the pressing load applied by the _ control 11 11 detected by the load detecting unit 14 satisfies the charge 4 reference (for example, 1 N) for presenting the tactile sensation. After the load is applied to the load reference, the tactile sensation presenting device drives the piezoelectric vibrating element of the illuminating portion 12 by a predetermined driving U, thereby causing the touch sensing n to be touched. The surface vibrates to stimulate the operator's touch. Borrow 23 201209692 This (pu:=: see ί set 9 can give the operator the same touch as the button touch when pressing the button switch (pushing the sense. Therefore 'off) ===Off: The operator can also obtain the operation of the actual button 11 "real press-down position, and can touch the touch sensing I by = pressing operation, so the operator will not feel uncoordinated. \Press this - with the pasta crane to control the sensor to order, so it can also prevent the operation of the miss. The driving signal of the rate and sense, that is, the fixed frequency of the stimulating touch ί / ^ ί The amplitude may be appropriately expressed according to the presented sensation, and the tactile sensation represented by the metal dome switch H m ^ (10) ^ for the mobile terminal is represented by, for example, by including a 140 ^ mobile salt frequency of //4 ~ Μ 任 - cycle _ moving signal to the part ^ 卩 U. The driving feeling is driven by such a driving signal. (4) = The surface vibration is about ΐ5 μιη in a state where the load of the load (four) is applied. Thereby, the operator can be presented with a realistic touch when the actual button is pressed. In the present embodiment, the tactile sensation control unit 30 monitors the pressing load of the contact __ u of the load detecting unit. Further, the touch-sensing portion 3G notifies the touch controller 11 that the load is detected by the load detecting unit 14 by "increasing and satisfying the predetermined load reference." Then, the contact position of the host controller 40 u is determined to be the position of the target that should present the tactile sensation, and if it corresponds to the position of the target, the tactile sensation is displayed 24 201209692 Ξ 制 30. Thus 'on the host control When the device 40 receives the touch of the sense, the touch control unit 3G generates a drive signal by generating a miscellaneous weight (4) sequence and (4) a drive signal, and the touch control unit 30 can also generate the drive signal. Since the machine control (4) 4G has an indication of the tactile presentation (_indication), when the pressing load satisfies the specified load base material, (the timing is not coincident with the time at which the scanning signal is generated), the touch is further generated. The detecting unit 14 can press the load by the value of the output of the plurality of piezoelectric elements. For example, the pressing load that satisfies the predetermined radiation standard is preferably set in advance according to the pressing load when the operator performs the normal pressing operation. 1 N ( The value of the value can be changed, and then the setting can be changed. Moreover, if the operator does not unconsciously touch the touch sensor, it is not determined that the pressing load has satisfied the prescribed load reference ' It is preferable not to set a value that is too low for the prescribed load reference. Further, in order to give the operator a pressure feeling for the above-described true touch, it is preferable to take into consideration the usual pressing load of the operator-conscious pressing (for example, In addition, the above-described predetermined load reference is set to a value that is too low. Thus, according to the tactile sensation presenting device 9 of the present embodiment, not only the tactile sensation of the third embodiment or the fourth embodiment can be obtained. The same effect is obtained, and the operation error can be prevented and the actual tactile sensation can be further exhibited. Further, in the tactile sensation presenting device 9 shown in FIG. 10, the tactile sensation presenting portion 12 and the load detecting portion 14 are additionally used. The tactile sensation presenting device 9 of the present embodiment is not limited to such a configuration. For example, the haptic presentation device 9 may be formed of a piezoelectric element or the like.

In other words, when the same component of the piezoelectric element or the like detects the pressing load on the touch sensor u and the pressing load satisfies the predetermined load reference, the touch sensor 11 can be vibrated to present the prescribed value. Touch. In this way, the constituent elements inside the casing of the apparatus can be disposed. At this time, the tactile sensation control unit 30 controls the timing so that the operation of detecting the pressing load of the touch sensor u by the load detecting unit 14 and the operation of generating the drive signal by the drive signal generating unit 32 do not match in time. , ^ This, you can use the same component to distinguish between its use. . Further, the present invention is not limited to the above embodiments, and may be modified in some ways. For example, in each of the above-described embodiments, the touch sensor control unit 2G and the tactile sensation control unit 3 are described as separate constituent elements. However, the touch sensing device of the present invention is not limited to such a configuration. For example, the touch sensor control unit 2 may be touched, and the control #30 is a single-chip structure. Controller. Other components may be combined with a plurality of components to form a single bull's structure, or a plurality of components may be separated from each other, and in any of the above embodiments, any number may be used. The piezoelectric vibrating element constitutes a vibration in which a transparent piezoelectric element is provided on the entire surface to constitute a current touch, and the financial composition is:

Come to form. Further, the load detecting unit 14 can detect the load according to the input detection method of the touch sensor, for example, in the case of the resistive film method, as long as the load can be detected based on the change in the output signal based on the change in resistance caused by the contact area. It is constructed using a strain gauge (10). Alternatively, in the case of the capacitive mode, the load detecting unit 14 can be configured without using a strain gauge sensor as long as it can detect the load based on a change in the output signal based on the change in capacitance. Further, in the tactile sensation presenting device of the fifth embodiment, when the pressing load detected by the load detecting unit 14 satisfies the load reference for presenting the tactile sensation, the tactile sensation presentation unit 12 is driven. However, when the pressing load detected by the load detecting unit 14 satisfies the load reference for presenting the tactile sensation, the pressing load detected by the load detecting unit 14 may reach the reference value for presenting the tactile sensation, or may be detected by the load. When the pressing load detected by the unit 14 exceeds the reference value for presenting the tactile sensation, the reference value for presenting the tactile sensation may be detected by the load detecting unit 14.
